Noticing federal prison flow from "Federal Justice Statistics, 2017-2018"

I often blog about the "stock" of federal prisoners (examples here and here and here), aided by the weekly reporting on the number of federal inmates by the Federal Bureau of Prisons at this webpage.  But, without information about the "flow" of persons in and out of prison, any snapshot of the prison population at a particular moment only tells part of the data story of modern mass incarceration.  Helpfully, the Bureau of Justice Statistics has released this new lengthy report, titled ""Federal Justice Statistics, 2017-2018," which includes data on the flow of federal prisoners over one year.

I recommend this new BJS report for all federal criminal justice fans, as it includes all sorts of data about about all stages of criminal case processing.  And I found this passage especially interesting when thinking about federal prison populations:

In FY 2018, a total of 59,248 sentenced offenders were admitted to the BOP, of whom 47,620 had been committed by a U.S. district court (table 8).  The remaining 11,628 offenders were returning to federal prison for violating conditions of their probation, parole, or supervised release or were admitted for a reason other than a U.S. district court commitment. Most prisoners admitted to the BOP had been convicted of a drug offense (36%), and the majority of them received a prison sentence of more than one year (74%).

A total of 64,397 prisoners were released from federal prison in FY 2018, of whom 52,404 were released for the first time since their commitment by a U.S. district court.  From the start to the end of FY 2018, the number of federal prisoners declined by 5,419.  This included decreases in immigration offenders (down 3,180) and drug offenders (down 2,323) and increases in public-order offenders (up 953) and weapons offenders (up 477).

Table 8 in this document reported a total federal prisoner population of 167,034 at the state of Fiscal Year 2018, which means that significantly more than a third of the entire federal prison population "turned over" in just one year. (My sense is that the "flow" numbers are comparable in state prison systems, and that they are especially dramatic for jails where most persons a serving terms less than a year long.)
